一九六四年,在铁道部基建总局及各级领导的支持和帮助下,丰台桥梁工厂、铁道科学研究院、和铁路专业设计院共同协作,实现了底模振动、管道形成及环销式锚三项技术革新,试制了两片31.7米预应力铜筋混凝土梁,并对其他一些细节作了改进。这份资料共包括:(1)预应力钢筋混凝土梁底模振动工艺;(2)光面环销式锚;(3)管道形成工艺;(4)铁路钢筋混凝土桥梁防水系统等四项。本刊将分期予以刊载,供各单位参考。
In 1964, with the support and assistance of the Infrastructure Administration of the Ministry of Railways and leaders at all levels, the Fengtai Bridge Factory, the Academy of Railway Science and the Railway Design Institute collaborated to realize the vibration of bottom molds, the formation of pipes and the ring-type Three anchor technology innovation, trial production of two 31.7 meters of prestressed concrete beams, and made some other details of the improvements. The information includes: (1) the vibration mode of prestressed reinforced concrete beam at the bottom of the mold; (2) smooth ring bolt; (3) pipeline formation process; (4) railway reinforced concrete bridge waterproofing system. This issue will be published in stages for reference of all units.
